Are these good number?

 

looks great.

you dont want to drop below 140, and no variation more than 30 psi.

 

Good numbers, you're in good shape.

wow now that's being generous.. 140 is really low, and 30psi is a really huge huge variation.... stock gsr's should be at about 210, im not sure what LS's should be at, but there should not be more than 10 psi of variation..

yeah i realize that. I would rebuild much sooner than that but the Haynes manual says 140 psi is service limit.

 

notice... "service limit".... not "performance limit" a 140 psi engine would NOT be running anywhere even CLOSE to where it should be at

 

LS should be 199. My numbers were like the same as yours. You're good to go

 

My gsr of 150k hit 190psi across. I heard 200psi is for stock gsr's?

 

190 for a GSR is a lil low from what it should be. GSR's should be 213. Minimum of 135, and a maximum variation of 28.

 

My haynes manual says B18C1 stock should be 270.. Mine tested at 250 245 246 246

 

Well, freakn A. I hear 190psi for 150k is good from other fellow H-Techers. and now u say its bad? Who thinks otherwise?????

 

Oh no, I wasn't saying it was bad at all. It's definately not as low as some tests I've seen. And for 150K it's pretty good. I was just saying that it's a little under what it should be, that's all.

 

heck yeah those are good #s. im gettin 135-140 across the board with 157,000+ miles. darn boost! haha

 

A compression test means very little. Try a leakdown test, that will tell you much more than a compression test.

 

i had a compression test a few weeks ago i bought a car recently but it was a 94 gsr 130k miles it was 140-135-138 and like 124 or something i sold it to a lady that rebuilds hondas and sells them for 3000 and it was in pretty good cond besides the motor

 

i think it was due to a transmission getting screwed a few times i went deep into the tach i was racing and when i hit 4th the car reved to like 11,000 rpms a few times when i was racing on the 3rd time the tranny blew up 4th5th and reverse were melted together

 

btw im new on here from superhonda and whats the 100% next to my posts?

 

Why is there such a difference between the haynes and the helms figure for the gsr?
My helms manual says the nominal (new) compression in PSI for the GSR should be ~213 psi, the service limit is 135 and there should be less than 28psi variance.
I just did my compression test today and I got 232, 220, 232, 232 psi.

 

in my 95 gsr with 153k i got 200-200-200-200

Those are some high numbers. You should get it checked out.

 

on my 98 LS w/ 88k , i got 195-195-195-195... on all 4 they were actually between 195-200, but they were all the same....
